online balance divider in ledger is red, but matches account balance

[Jack]

I don't know if this is actually a recent change or if I just noticed  
it, but recently, in several of my credit card accounts, the "Online  
Balance" divider in the ledger is shown in read, even though the  
balance is identical to the balance of the account and of the balance  
of ledger item immediately above the divider.  Reconciliation dividers  
which match the balance of the ledger item immediately above them are  
correctly green.  The Online Balance divider is correctly green for a  
checking account.

Any thoughts on why I may be seeing this behavior?
